I got a good chuckle out of this.
About the only time temp cavity will cause damage is if it hits inelastic tissue like the Liver. Permanent cavity is the only thing seriously considering.
Note how the softpoint loads produce temporary cavities not much larger than their FMJ counterparts. However, the permanent cavity is much larger thanks to expansion and fragmentation.

Agree..... but with a bit of a caveat... If the temporarty cavity is as big as, or almost as big as, the body of flesh it is passing through, the temporary cavity can burst apart the body.
This can be seen if you shoot a racoon/possum size animal with a high power rifle. I once saw a possum shot with a 270 at a distance of ~ 40 yards. It was blown into 4 pieces and scattered over a six foot area.
A 50 BMG at close range can have a similar effect on human bodies.
A high power rifle hit to an arm of leg can cause a temporary stretch cavity that completely separates and shreds the muscle tissue from the bone. This can even happen with 5.56mm

The temporary cavity isn't going to do a whole lot to very many tissues. It does have a fine effect on things like the brain, spine, etc., but the effect may not be permanent, such as with Special Agent Gordon McNeill who was shot in the neck and the spine was not hit, but he was paralyzed for several hours.
Don't count on the temporary cavity making any sort of dramatic difference. Maybe it can, but it isn't consistent in how the target is affected.
